Apple's iCloud roll-out on Wednesday also features an update to its Lion operating system in the form of Mac OS X 10.7.2, bringing support for new cloud-based services like syncing, Back to My Mac, and Find My Mac.

Apple on Tuesday released Mac OS X 10.7.1, its first security and maintenance update for the newly released Lion operating system, with improved Wi-Fi reliability and resolutions for issues related to HDMI and optical audio output.

The Google+ software for iOS has been expanded to support the iPad and iPod touch. In addition, Skype for Mac version 5.3 has been released, adding support for Mac OS X 10.7 Lion, as well as high-definition video calls.

Multiple PayPal users have been incorrectly charged for purchasing Mac OS X 10.7 Lion from the Mac App Store numerous times, with one user claiming to have received a bill of nearly $4,000 for the $29.99 software.

Given the lack of an optical drive all of Apple's new MacBook Air and Mac mini models, the company has included a new "Internet Recovery" feature in its new operating system to reinstall Lion or initiate repairs on the latest Macs.

For those who want to have their copy of Lion saved on a physical medium, Apple will make the Mac OS X upgrade available on a USB thumb drive through its online store in August, but at a cost more than twice the price of the Mac App Store.
